"Ultracold quantum gases in triangular and hexagonal optical." lattices: unconventional magnetism and Graphene like physics

"Scientific News" (copied from: http://photon.physnet.uni-hamburg.de/de/ilp/sengstock/)"The research in our group mainly concentrates on two major topics. Experiments dedicated to the field of ultracold quantum gases are complemented by research activities in the field of fibre laser development and state-of-the-art ultra-sensitive spectroscopy.At temperatures close to absolute zero neutral atoms offer an ultimate degree of control over all system parameters. Bosonic, fermionic and mixed systems in trapping potentials of different geometry including e.g. optical lattices and hollow core photonic crystal fibres are realized in our group and offer the possibility to mimic pure quantum mechanical model systems over a wide range of interaction and correlation regimes.We are especially interested in laser cooling techniques, the physics of multi-component system pointing towards the investigation of e.g. quantum magnetism in frustrated geometries and other exotic quantum phases like e.g. composite particles made out of Bosons and Fermions in optical lattices.You will find descriptions of the individual research projects here."
